Water quality
Official status: Florida Healthy Beaches (Florida Department of Health) · Florida Department of Health in Brevard County
The state samples beach water for enterococci bacteria: Good 0–35, Moderate 36–70, Poor 71 or more per 100 mL. If a result is above 70 and a resample is too, the county issues an advisory for that site. We haven’t found an official machine-readable feed we’re allowed to reuse, so we link to the official results instead of showing a status.

Swell window for this beach (estimate)
Reaches well from: 20–140° · partly from: 141–165° (directions the swell comes from, degrees true). East-northeast-facing open Atlantic beach; the inlet jetties shape the waves nearby. Estimate only: bearings read from coastline orientation and generally known exposure, roughly ±15°, not surveyed.

Beach info
| Parking | Parking on both sides of the inlet; the north side fills up on busy weekends and holidays. |
| Showers | Cold-water showers. |
| Lifeguards | No lifeguards: the park says lifeguards are not provided. |
| Surf / swim rules | Pets are not permitted on the beaches. Alcohol is prohibited. |
| Good to know | The north-side cove is protected, with a gentle slope; the park suggests it for people who aren't strong swimmers. The first peak by the north jetty is one of Florida's most consistent surf breaks. |
